The Dual V-Mount to V-Mount & Gold Mount to V-mount Battery Adapters (SKUs: 7718 & 7719) will work with most 14.4V/14.8V batteries. The Dual Battery Adapters were designed with a unique configuration allowing two batteries to connect in series, therefore allowing a fully-charged pair of batteries to create a voltage up to 33.6V, or a nominal voltage of 29.6V. The Dual Battery Adapters allow most 14.4V/14.8V V-mount or Gold Mount batteries to be fully compatible with both the Flex Cine and Flex Wireless DMX Dimmers.
Please Note: It's highly recommended that both batteries be of the same voltage type and charged to a similar level to maintain peak efficiency.
